Answer:
Range = 22.61 m
Explanation:
We can use the formula for the Range in flat ground, given by:
which for our case renders:
In order to compute the final velocity of the trains, we may apply the principle of conservation of momentum which is:
initial momentum = final momentum
m₁v₁ = m₂v₂
The final mass of the trains will be:
10,000 + 10,000 = 20,000 kg
Substituting the values into the equation:
10,000 * 3 = 20,000 * v
v = 1.5 m/s
The final velocity of the trains will be 1.5 m/s

It makes it easier to dig a hole because it helps pick up dirt
This is all related to the centripetal force. Rememeber that In uniform circular motion, velocity changes due to change in direction, eventhough magnitude remains constant. having that in mind we know that <span>She should change the direction of the vectors that are toward the center of the circle so that each points away from the center of the circle.</span>
